NEET Physics Newton's Law of Cooling MCQ Question
A hot object at temperature T_2 is placed in a large room with a constant temperature T_1. According to Newton's Law of Cooling, which of the following expressions represents the rate of cooling of the object?
-k(T_2 - T_1)
k(T_2 + T_1)
-kT_2
kT_1
Correct Answer
Detailed Explanation
Newton's Law of Cooling states that the rate of cooling is proportional to the excess temperature of the body over the surroundings, represented as -k(T_2 - T_1), where k is a positive constant.
